I have the Nano K5 which is essentially a 5inch driver version sans BT. They are typical of Studio monitors which means, it is meant to be listened in short distances (i would say less than 3 mts distance) and On Axis positioning for best effect. The speakers are actually sweet sounding and wave guide on Tweeter gets you pretty decent imaging as well. I personally found a bass to be tight and smooth but it lacks outright punch. With a good DAC+Preamp combo, it really punches above its weight in small listening spaces. Even though they are sealed units, its better to leave 1-2 ft space on back and sides of this speaker.
